Ruby script can't use gem

I have a tiny, plain (i.e. non-Rails) Ruby project that I'm trying to get to work with the addressable gem. Here's what happens:

$ ruby -r rubygems sign.rb
sign.rb:5:in `require': cannot load such file -- addressable (LoadError)
    from sign.rb:5:in `<main>'

This is the Gemfile:

source "http://rubygems.org"

gem "addressable", "~> 2.3.2"

This is sign.rb:

#!/usr/bin/env ruby

require "rubygems"
require "bundler/setup"
require "addressable"

That's all there is to it. Why doesn't it want to use the gem?

There is no addressable file that you can require, just the addressable directory. You need to require the specific file under that directory you want, e.g.:

require 'addressable/uri'
uri = Addressable::URI.parse("http://example.com/path/to/resource/")
# etc ...

or

require "addressable/template"
template = Addressable::Template.new("http://example.com/{?query*}/")
# etc...

Check out the addressable docs.

Have you installed the gem previously by using $ bundle install ?

This will fetch the gems specified in your Gemfile and make them available to the working directory.
